Abstract

A triple band mmWave microstrip antenna on low-cost FR4 substrate is proposed in this paper. The triple band is achieved using Sierpinski fractal structure with an optimized ground plane. The resonances observed are at 29.05 GHz, 35.75 GHz and 41 GHz with 10 dB impedance bandwidths of 4 GHz, 2.06 GHz and 2 GHz respectively. These bands fall into the candidate bands for upcoming 5G applications. The proposed unloaded triple band antenna has low gain throughout these bands, hence a uniplanar optimized EBG structure is proposed for gain enhancement across the intended bands of operation. The reflection-phase of various structures of EBG unit cells were characterized to obtain the optimum design. The optimum unit cell was loaded onto the triple band antenna to obtain Peak Gain of 2.37 dBi and 17.37 dBi in the 28 and 38 GHz bands, respectively. The proposed EBG loaded antenna is fabricated and characterized.

低成本高增益三波段毫米波Sierpinski天线加载单平面EBG用于5G应用

本文提出了一种基于低成本FR4衬底的三波段毫米波微带天线。采用Sierpinski分形结构和优化的地平面实现了三频带。观测到的共振频率分别为29.05 GHz、35.75 GHz和41 GHz, 10 dB阻抗带宽分别为4 GHz、2.06 GHz和2 GHz。这些频段属于即将到来的5G应用的候选频段。所提出的卸载三波段天线在这些波段具有低增益，因此提出了一种单平面优化的EBG结构，用于在预期的操作波段上增强增益。对不同结构的EBG单元胞的反射相位进行了表征，得到了最佳设计方案。将优化后的单晶片加载到三频段天线上，在28 GHz和38 GHz频段分别获得2.37 dBi和17.37 dBi的峰值增益。制作并表征了所提出的EBG负载天线。
